Retroperitoneal synovial sarcoma presenting as paraneoplastic hypoglycaemia

Synovial sarcoma is a well-recognized malignant mesenchymal neoplasm. Primary retroperitoneal synovial sarcoma is extremely rare and has poor prognosis. There are sparse reports in the literature on the secretory synovial sarcomas. In this report, we present the case of a patient with retroperitoneal synovial sarcoma who presented with recurrent attacks of hypoglycaemia.
